Our new, better frequency is not ready yet (see issue #11), and many
users have built some muscle memory from their years of typing
Cangjie/Quick on that other Operating System.
Let's use that older, worse ordering for now, and we'll see later on how
to introduce the new one.

IBus Cangjie is not really a library, so the going with LGPL instead
of plain GPL doesn't make much sense in retrospect.
I asked Benau (the only contributor other than myself) and he agreed
in an email.
So all copyright holders agreed, and from now on, IBus Cangjie is
distributed under the GPLv3+.
